This product is effective to catch moths. I discovered in the textile company where I work and lately I use at home. This is the principle of self-adhesive rollers or stick flies in time without the drawback: it is in a box, it is not ugly and actually this only attracts moths. I bought it because I had seen flying one or two moths, and I had the surprise to see that after about 2 days, there were a dozen visibly catching numerous in this spring! The only slight downside to this product (4 out of 5 stars) is for installation: after removing it from its case, you must slide the self-adhesive plate impregnated with the product in the receiving box of 2cm thick, of course if the top of the box is touched, if the plate glue. He must quickly take off for the slide and press it on the bottom of the box, which is of course possible. Let's say if we have done the first time, next time I'll be careful and it will be no worries. Very good product, I rachetterai
